Comparator 1 Limit Error

What does CP1 mean?

This fault activates when the monitored value, selected in H2-20 [Comparator 1 Monitor Selection], falls within the predefined range set by H2-21 [Comparator 1 Lower Limit] and H2-22 [Comparator 1 Upper Limit]. It signals that a critical process variable has entered a restricted operating window, indicating an abnormal condition that requires immediate investigation to prevent operational issues.

Additional Steps
